摘　　要：测定拉伸试验机的系统柔度在试验机速率控制方面起着重要的作用。传统的试验机柔度测定方法在试验条件等方面有很大的局限性,而且试验过程比较复杂。从速率和能量两个不同的角度,探讨了系统柔度的计算方法,提出了两种全新的系统柔度的测定方法,同时利用Origin科学计算软件对试验数据进行处理,可以更加准确方便地测定拉伸试验机系统柔度。The measurement of the system compliance of tensile testing machine plays an important role in controlling over testing machine speed. Traditional compliance measurement method for testing machine, with complicated testing process, is greatly limited in aspects such as testing conditions. The paper discusses the calculation method of system compliance from two different perspectives, i.e., testing speed and energy, and proposes two new methods of measuring system compliance, which, with ORIGIN, a science calculation software, processing test data, measure and determine the system compliance of tensile testing machine in more accurate and more convenient ways.
